Emerging Options for Water and Wastewater Disinfection


0.6 CEUs


This one day course will cover both current understanding of the established technologies and the possible impacts of the emerging disinfection technologies.

There are a number of new and emerging disinfection technologies that are available for water and wastewater disinfection. It is important for operator personnel to understand the applicability of these options to meet today's and potential tomorrow's regulatory requirements. For each technology, there are associated differences in pathogen removal, disinfection by-product formation, treatment facility energy use and operating costs, input chemical requirements, and supply chain impacts.

This course is presented by Lalith Liyanage, Ph.D., P.Eng. of WSP Group, a globally recognized professional services firm as well as the owner of Aqualta School of Operator Training.

The CEUs from this course can be used toward the following discipline(s) for certification renewal:

• Water treatment
• Wastewater treatment
